23 | .SH DESCRIPTION | |
c13182ef | 24 | The \fBwcscmp\fP() function is the wide-character equivalent |
fb186734 | 25 | of the \fBstrcmp\fP(3) function. |
c13182ef | 26 | It compares the wide-character string pointed to by \fIs1\fP and the |

27 | wide-character string pointed to by \fIs2\fP. |
28 | .SH "RETURN VALUE" | |
e511ffb6 | 29 | The \fBwcscmp\fP() function returns zero if the wide-character strings at |
c13182ef MK |
30 | \fIs1\fP and \fIs2\fP are equal. |
31 | It returns an integer greater than zero if | |
fea681da | 32 | at the first differing position \fIi\fP, the corresponding wide-character |
c13182ef MK |
33 | \fIs1[i]\fP is greater than \fIs2[i]\fP. |
34 | It returns an integer less than zero if | |
fea681da MK |
35 | at the first differing position \fIi\fP, the corresponding wide-character |
36 | \fIs1[i]\fP is less than \fIs2[i]\fP. | |
